Climate change has resulted in the outbreak of infectious diseases especially vector-borne diseases around the globe, discuss. (use at least two specific examples)

Arsenic in drinking water is bad, discuss.

Expert Solution

The simplest linkage between vector-borne diseases and climate are through these factors:

Temperature (Determines the growth and survival of the pathogens)
Reproductive rates of the vectors (Indicates the multiplication of the microbes)
Development rates of the pathogens
Precipitation (Transmission of diseases by vectors that possess an aquatic developmental stage for eg. mosquitoes)
Humidity( diseases transmitted by vectors for eg. ticks )
Changes in the adaptations of the pathogens due to climate change

Emerging infectious diseases are those infections that have a new origin in a population, or are quickly increasing in incidence. Typically, these are caused by animals (60-70%) and the causative agent can be a newly appeared pathogen)

Reemerging diseases are those infections that again appears in the population after a short phase of disappearance in a population. (Such as Dengue, plague, yellow fever)

Arsenic in drinking water affects the body

1.Long-term exposure to arsenic in drinking water can cause( cancer in the skin, lungs, bladder and kidney.)

2. skin changes such as thickening and pigmentation

3. Arsenic is highly toxic in its inorganic form.

4. vomiting, abdominal pain and diarrhoea

Think about water. Think about how it is tied in with waste and vector borne diseases. Humans have been using water as a way for disposing waste for centuries! Vector-borne diseases account for more than 17% of all infectious diseases, causing more than 1 million deaths annually. We take water so much for granted yet it is many times the source of many public health issues. Give an example of why we need to be concerned with vector-borne diseases and...

"Global Climate Change" refers to shifting trends in the long-term weather patterns ("climate") across the globe, and includes phenomena such as global warming. At its root is a steady increase in the atmospheric concentration of several gases called "greenhouse gases", some of which are released through burning fossil fuels such as gasoline, coal, and natural gas. One greenhouse gas is carbon dioxide, an input for photosynthesis and an output of cellular respiration. Your assignment for this Discussion Board to is...

Climate disruption is causing major changes in environmental conditions around the globe. What sorts of changes are expected in the region where you live? What are some likely consequences in your region? What types of mammals appear to be most at risk in the region where you live?

Has the focus on disease prevention and health promotion shifted from infectious diseases to chronic diseases?...

Has the focus on disease prevention and health promotion shifted from infectious diseases to chronic diseases? Why or why not? Will a diversion in focus from infectious to chronic diseases leave the United States and other parts of the world at greater risk for pandemics or bioterrorism? Why or why not? How do risk factors and prevention strategies differ from infectious and chronic diseases? When thinking about chronic diseases, how do you perceive the purpose and utility of passive surveillance...

Globalization has had a great impact on various issues i.e. urbanization and health, emerging infectious diseases, food safety and security, and global environmental change. Select ONE issue that concerns you the most, providing a detailed discussion on the impact of globalization, highlighting the pros and cons. Discuss ONE current strategy in place to mitigate the negative impact. What is your opinion on this strategy?

UCSF has hired you to summarize the effects of climate change on the emergence and transmission of pathogens. In your summary please highlight how climate will influence populations and communities of pathogens and hosts, including the role of host behavior in transmission. You may make comparisons to other diseases. Be sure to identify what ecological principles lead you to your hypotheses and what experimental evidence suggests that principle is true.

The Goldman Fund has hired you to summarize the effects of climate change on plant and animal species found in California. In your summary, please highlight what changes you might expect to see under global warming for different types of species and communities in California. You are not expected to speak to specific species, instead think of broad categories (e.g nectar feeders or primary producers). Be sure to identify what ecological principles lead you to each of your hypotheses and...
